A laptop wakes after the room’s replay window has expired. The gateway returns recent events after the old cursor, leaving an invisible gap in the task state.
Estimated field mix
A responder claims Investigate cache saturation, loses the acknowledgement, and retries. The room appends duplicate claims and briefly shows two owners.
Estimated field mix
Closing a laptop leaves its user shown as In room for hours. Presence currently uses the same durable event path as incident notes, making heartbeat traffic dominate replay.
Estimated field mix
A temporary responder is removed while a long history replay is streaming. The established socket keeps receiving new private notes until reconnect.
Estimated field mix
A paused browser cannot consume events, but its send buffer grows throughout a synthetic incident drill. Add bounded per-connection delivery and a recoverable overload path.
Estimated field mix
The team has not tested what room users see during a gateway restart. Create a repeatable drill with one pending claim, a disconnected reader, and a recently revoked member.
Estimated field mix
Missing coordinates are coerced to zero, placing a depot van in the ocean. Validate telemetry before rendering and explain vehicles with no usable position.
Estimated field mix
A van’s last position remains bright green after its device disconnects. Dispatch assigns a nearby job using a point that is twenty minutes old.
Estimated field mix
A synthetic depot near the date line has vans at longitudes 179.8 and -179.7. Fit selection zooms to the whole world because the bounding box takes the long route.
Estimated field mix
A device buffers updates through a tunnel, then sends them out of order. The marker jumps to an older point and the arrival-age label resets incorrectly.
Estimated field mix
The dashboard downloads a vehicle snapshot and opens the live stream afterward. Updates during that gap never arrive, so a van appears stale until its next fix.
Estimated field mix
Two dispatchers assign the same van to different pickup jobs. Both dashboards show success until a refresh reveals the losing assignment disappeared.
